It just shows you that this monitor is just "some preview". Don't expect more. Has BM added low pas filtering to 4K model? If not then these scopes are about useless as you will have misleading results with overshoots. Check it against Tektronix.

It all depends what you use it for.If it's same old model then there is no low pass filtering, so you will be seeing things going over 100% where in reality these are just overshoots and should be filtered. It was confirmed by BM that it's hardware limitation and can't be "fixed". If you have Tektronix you can flip low pass filtering on/off and see what difference does it make.Smartscopes are unreliable, specially when used for broadcast, eg. QC. Atomos is probably the same.
